Automatic reading and writing method of vehicular calibration signal and vehicle calibration method

An automatic reading and writing method of a vehicular calibration signal, comprising:

• creating mapping system variables respectively for calibration signals in a calibration module;
• assigning an initial value to the mapping system variables;
• for a calibration signal defined as a calibration variable, associating an assignment function to an asynchronous function, wherein the assignment function is a mapping system variable write function of a to-be-written target value;
• when the calibration variable is written, distributing, by the asynchronous function, a write command and a read command to the calibration module, and returning immediately, wherein a call of the asynchronous function is completed;
• and/or,
• for a calibration signal defined as a writable observation variable, associating an assignment function to an asynchronous function, wherein the assignment function is a mapping system variable write function of a to-be-written target value;
• when the writable observation variable is written, distributing, by the asynchronous function, a write command and a read command to the calibration module, and returning immediately, wherein a call of the asynchronous function is completed.
